Arise lets you customize alarms to fit your personal way of waking up well.
It adds a volume slider to each alarm: No more oversleeping due to a too silent ringtone.
For a easier morning you're able to set up an auto-dismissal timer or add a smooth fade-in, which gradually increases the volume from 0 to your desired value.
Complete localization and seamless integration makes it fit perfectly into the native Clock.app.
